Automating VM image building with Packer	Use Packer to build custom VM images, configure VMs and work with remote OCI registries.

Please refer to Tart Packer Plugin repository for setup instructions. Here is an example of a template to build a local image based of a remote image:

packer {
  required_plugins {
    tart = {
      version = ">= 0.5.3"
      source  = "github.com/cirruslabs/tart"
    }
  }
}

source "tart-cli" "tart" {
  vm_base_name = "ghcr.io/cirruslabs/macos-tahoe-base:latest"
  vm_name      = "my-custom-tahoe"
  cpu_count    = 4
  memory_gb    = 8
  disk_size_gb = 70
  ssh_password = "admin"
  ssh_timeout  = "120s"
  ssh_username = "admin"
}

build {
  sources = ["source.tart-cli.tart"]

  provisioner "shell" {
    inline = ["echo 'Disabling spotlight indexing...'", "sudo mdutil -a -i off"]
  }

  # more provisioners
}

Here is a repository with Packer templates used to build all the images managed by us.
